To aZZ whom t may concern.'

Beit known that l, CHARLES M. Harmsen, a citizen of the United States, residing at Wilton Junction, in the county of Muscat-ine and State of owa, have invented new and useful Improvements ,in Cultivator Attachments, of which the following is a specification.

This invention relates to an attachment for cultivators, the object of the inven-` tion being to provide an attachment which niav he connected with the gang frame yoke and is provided with a circular and rotatable' member for arrangement adjacent the forward shovelto serve as a. shield to prevent young plants from being coveretL or broken by the dirt "thrown, up oy the shovel when the cultivator is in use.

Another object of the invention is to provide the. atttachment with a circular shieldI which is so constructed that when the cultivator is in use the earth turned up hy the shovel may pass through the shield and onto the roots of the young .lants while clods and the like, will yhe loro en in their passage through the shield or deflected away from the plants.

With these and other objects in view, the invention resides in the novel combination and arrangement of parts, which will he hereinafter described and particularly pointed out in the claim.

. therefore reserve theright to make anyT changes as fairly fall ,under the scope of my claim Without the changing of my in-l vention. f

The preferred embodiment of the invention has been illustratedl in the accompanying drawing, although no restriction is necessarily made to the precise details or construction therein shown', as changes, ahteraftions,

and modifications, within the scope of the claim may he resorted to'when desired.

Like characters of reference denote correspending parts throughout the several views in the drawing, in which:

Figure 1 is a vertical longitudinal sectional 'view through a portion of the cultivater showing the attachment connected therewith.

Fig. 2 is a view in elet/ation of the attachment showing the samev disconnected from the cultivator.

Fig. 3 is a horizontal t transverse section on the line 3--3 of Fig. 2.

Referring now to the drauihg in detail, t-he numeral l designates a portion o' a cultivator of the double-row type to the gang frame yoke 2 or which is connected a gang frame 3 having connected therewith the Shanks of shovels #l in the usual manner.

An extensible arm 5 has one end pivotally connected with, the gang frame yoke 7 and its other end provided with a stub-shaft 6 arranged at right-angles to said arm and receiving` thereon a circular and reticulated shield 7 arranged adjacent the forward shovel et on the gang frame 3 and rotatable upon the stub shaft G through the contact of the shield 7 with the ground with which it is held in engagement by the weight of the arm'.

The shield or fender comprises a frame 8 formed with a central portion 9, and lfour radially extending arms ll. The frame is mounted on shaft 6 supported in hearings 10, and one of the arms is provided with a douhle row of apertures 13, the remaining: arms having' a single row of apertures l2. A plurality oi independent curved Wires or rods form a series of concentric and approximately annular elements or members 14, the ends of the separate wires being connect-ed with that radial arm haring` the apertures 13. The wires pass through correspondinely located apertures oit the remaining arms, entering at one side of a given arm, and passing thence from the opposite side to the next arm. Corresponding enges of the arms are unobstructed, and the wires le are oset or deflected at 15 adjacentto the apertures l2 through which they pass. These offset or deflected portions tend to maintain the Wires in their original position and relieve strain on the end connections of said wires.

A tread element lo is secured to the ends of the radi-al arms by means of eye members 17.

V`With an attachment constructed as above described and connected with a cultivator as shown in Fig. 1 in the drawing, it will be seen that when the cultivator is in use, the earth `thrown up .by the forward shovels @L is directed against the reticulated shield 7 through which said earth may 'pass and fall 'upon the roots of the plants while clods or lumps of earth which would tend to break or injure the plants would be hrolren through their contact with the hands lll and the rotation of the shield or deflected away from the plants,

From the foregoing description, taken in connection with the accompanying drawing, it is at once apparent that an attachment for a cultivator has been provided Which is simple in construction, therefore inexpensive of manufacture, although highly efficient in use. l

Having thus described the invention, what is claimed as new, is: In a device of the class described, a frame including a pluralityv of arms radiating from a common center, an eye member carried by' the end of each arm, a tread element passing through all of the eye members and extend- Copies of this patent may be obtained for ingcircumferentially of .the device, aphn 'ality of concentric members of Aapproximately annular form havingJ end portions approaching each other and connected with one of the arms, the remaining arms being each provided with a series of apertures, and the concentric members passing through corresponding' apertures in each series, and :from a given side of each arm to the opposite side of an adjacent arm and being offset near the respective arms, corresponding edges of the arms being unobstructed.

In testimony WhereotI I ai'lix my signature.

CHARLES M. HARMSE.
